Flexible Display Housing for Variable Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with mechanical keypads face limitations in portability and screen size expansion, as the mechanical keypad occupies space that could be used for a larger display.
Innovation Solution
An electronic device featuring a flexible display that can change its visible display area size by moving parts of its housing, allowing for the display of multiple applications across different areas of the screen as the size changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a larger display is mounted to the electronic device, then the screen size is improved, but the portability deteriorates
Solution Approach 1:
The display transitions from a static fixed size to a dynamic variable size through flexible materials and mechanical movement structures, allowing the display area to be adjusted between extended and retracted states, thus resolving the contradiction between large display area and portability
Solution Approach 2:
The display is moved from a two-dimensional plane to a three-dimensional configuration that can extend beyond the housing boundaries, utilizing spatial dimensionality to increase display area without proportionally increasing the device's footprint when retracted
2Area of stationary object
If the display area is expanded, then the multimedia function is improved, but the device size increases
Solution Approach 1:
The flexible display is nested within the housing structure, allowing it to be stored compactly within the device boundaries when not in use, and extended outward when needed, thus providing large display area without permanently increasing device volume
3Area of stationary object
If a mechanical keypad is removed to expand display area, then the screen size is improved, but the input function deteriorates
Solution Approach 1:
The display serves multiple functions by being both the visual output interface and the input interface through touch capabilities, eliminating the need for separate mechanical keypads while maintaining input functionality, thus resolving the contradiction between display area expansion and input function preservation

AI summary
An electronic device is provided. The electronic device includes a housing, a flexible display in which a size of a display area visible from outside of the electronic device is variable from a first size to a second size based on moving of at least part of the housing, memory storing one or more computer programs, and one or more processors communicatively coupled to the flexible display and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to display an execution screen of a first application in a first area of the flexible display in a state that the size of the display area is in the first size, while the display area is changed from the first size to the second size, display at least a portion of the execution screen of the first application or a simplified screen of the execution screen of the first application, in a second area including at least a portion of the first area, and while the size of the display area is changed from the first size to the second size, display an execution screen of a second application, corresponding to the size of the display area, in a third area including at least a portion of a display area newly visible from the outside of the electronic device, and wherein a velocity at which the execution screen of the second application is displayed, corresponding to the size of the display area, is different from a velocity at which a size of the display area is changed.
